【発明の詳細な説明】 物理的性質を変化させたアルギネート 本発明は機能性、特に無機および有機多価イオンによるゲル形成能力について変 化を得るためにアルギネートおよび他のウロン酸物質を修飾する方法に関する。[Detailed description of the invention] Alginate with changed physical properties The present invention has been modified in terms of functionality, particularly the ability to form gels with inorganic and organic multivalent ions. The present invention relates to a method for modifying alginate and other uronic acid materials to obtain oxidation.
アルギネートは褐藻海藻類から製造され、これらの多価電解性が例えばゲル化、 増粘および水−およびイオン−結合に対する基礎を形成するいくつかの適用に利 用される。Alginates are produced from brown seaweeds, and their polyelectrolytic properties result in e.g. gelation, Useful in some applications forming the basis for thickening and water- and ionic-bonding. used.
化学的には、アルギネートはβ−D−マンヌロン酸(M)およびそのC−5エピ マー、α−L−グルロン酸(G)から形成される1群の直鎖、二元共重合体を構 成する。MおよびGユニットは3種のタイプの配列で見出される。G−ブロック と呼ばれるGの豊富な配列、M−ブロックと呼ばれるMの豊富な配列、およびM G−ブロックに見出される交互の配列、MGMGとして記号化されるものである 。これらのモノマー ユニットおよびこれらの配列配分のフラクション含量は海 草起源により変化する。イオン結合およびゲル形成性はモノマーフラクションに 依るが、特に鎖に沿うG−ユニットの配分による。G−ブロックの高含量は技術 上ff要なゲル形成性に導く。Chemically, alginate is composed of β-D-mannuronic acid (M) and its C-5 epi A group of linear, binary copolymers formed from α-L-guluronic acid (G) to be accomplished. M and G units are found in three types of arrangements. G-block G-rich sequences called M-blocks, M-rich sequences called M-blocks, and M-rich sequences called M-blocks. The alternating sequence found in the G-block, symbolized as MGMG . The fractional content of these monomer units and their sequence distribution is Varies depending on grass origin. Ionic binding and gel-forming properties are determined by the monomer fraction. It depends, especially on the distribution of G-units along the chain. High content of G-block is technology Leads to the necessary gel-forming properties.
本発明の目的はこれらの物理性を変えるために、オリゴマー又はポリマーのM− ユニットをG−ユニットに転換することである。もとの完全なポリマーのこのタ イプのエンド−エピマー化はマンヌロナンC−5エピメラーゼ、アルギネートの 生体内住合成に関与する酵素(出願番号845059参照)によりアルギネート を処理することにより行なうことができる。The purpose of the present invention is to modify the M- It is to convert a unit into a G-unit. This type of original complete polymer The endo-epimerization of alginate is carried out by mannuronan C-5 epimerase. alginate by enzymes involved in biosynthesis (see application number 845059). This can be done by processing.
本発明によれば、いくつかのポリサッカライド生産微生物からの酵素方法として 周知のこのようなエピマー化は酵素がなくても行なうことができる。この種の方 法は、カルボアニオン(C−5における電荷)を生成する;]−5のアルカリ触 媒抽出は水の存在でポリマー鎖の加水分ネート)は非極性溶媒に不溶性であり、 従って非プロトン性溶媒中の反応は実施が困難である。According to the present invention, as an enzymatic method from some polysaccharide producing microorganisms Such epimerization, which is well known, can be carried out without enzymes. This kind of person The method produces a carbanion (charge at C-5); Solvent extraction is the presence of water in which the polymer chains (hydronate) are insoluble in non-polar solvents; Therefore, reactions in aprotic solvents are difficult to carry out.
本発明は超臨界條件下で二酸化炭素により固体状態でアルギネートを処理するこ とにより上記問題を排除する完全に新しい原理に基づく。この條件は密度は液状 であるが、拡散速度はガス状態における場合と同じである。The present invention involves treating alginate in the solid state with carbon dioxide under supercritical conditions. and is based on a completely new principle that eliminates the above problems. This condition means that the density is liquid However, the diffusion rate is the same as in the gaseous state.
その場合CO2は非プロトン性溶媒として、および触媒としての双方でH−5の アルカリ除去に作用しC−5カルボアニオンを形成することができる。高圧はシ アキシアルに(diaxially )結合したG−ユニットが一層緊密な鎖構 造、従ってジイクアトリアルに(dtequatorially)結合したM− ユニットと対比して低級部分モル容積を与えるように、効果的にエピマー化に寄 与する。ざらに非プロトン性溶媒中で7ノマー効果はアルギネートのα−一層有 利にする。In that case CO2 is used both as an aprotic solvent and as a catalyst for H-5. It can act on alkali removal and form a C-5 carbanion. High pressure is The axially bonded G-units form a tighter chain structure. structure, thus diquatorially coupled M- effectively contribute to epimerization, giving a lower partial molar volume relative to the unit. give In roughly aprotic solvents, the 7-nomer effect is more pronounced than in alginate. Make profit.
出発材料として海草又は細菌起源のアルギネートを塩(アルカリ又はアルカリ出 金属形)、エステル又は他の酸誘導体のいずれかで選択することができる。Alginate of seaweed or bacterial origin is used as a starting material with salt (alkali or alkaline extract). (metallic form), esters or other acid derivatives.
超臨界二酸化炭素の適用は従来は不活性溶媒として超臨界流体を使用して例えば アロマ化合物の抽出内で主として見出されるエイチ・コーネンとイー・クリ−ゲ ル、食品工業における超臨界ガス抽出の利用(H,Coenenand E、 Kriegel、[Uses or 5upercritical Ga5Ex tracNon in the Food Industry J 、ムChe i+、 肋1Tech、 55 (1983) 890 ) 。本発明に対する 基礎を形成する発明はポリサッカライドの非酵素的、化学的エピマー化の最初の 既知例および化学反応における触媒および溶媒の双方として超臨界流体の最初の 適用である。本発明は固体状態の材料に適用できることでこの種の酵素的および 大部分の他の既知化学的修飾方法とも異る。記載の既知方法は稀薄溶液(〈1% )を必要とし、そして生成物は沈澱させ、精製し、費用のかかる方法で乾燥しな ければならない。Applications of supercritical carbon dioxide have traditionally been performed using supercritical fluids as inert solvents, e.g. H. Konen and E. Kriege found primarily within the extraction of aromatic compounds. Utilization of supercritical gas extraction in the food industry (H, Coenenand E, Kriegel, [Uses or 5supercritical Ga5Ex tracNon in the Food Industry J, Mu Che i+, Rib 1 Tech, 55 (1983) 890). for the present invention The underlying invention is the first non-enzymatic, chemical epimerization of polysaccharides. Known examples and first examples of supercritical fluids as both catalysts and solvents in chemical reactions It is application. The present invention can be applied to solid-state materials to enable this type of enzymatic and It is also different from most other known chemical modification methods. The known method described uses a dilute solution (<1% ), and the product must be precipitated, purified, and dried in an expensive manner. Must be.
本発明では超臨界條件下で圧力を変えて(150〜500バール)使用するCo 2によりアルギネートを処理し、試験條件は変化に反映させたが、有意なエピマ ー化、ゲル強度の相当する増加はエピマー化に随伴した。従って、結果は超臨界 二酸化炭素処理によりグリクロナンス又は相当するオリゴサツカライドのC−5 エピマー化は炭水化物の化学的修飾に対する完全に新しい方法を供することを示 唆する。In the present invention, Co The alginate was treated according to 2, and the test conditions were reflected in the changes, but no significant epima was observed. -ization, a corresponding increase in gel strength accompanied epimerization. Therefore, the result is supercritical C-5 of glycronanthin or corresponding oligosaccharide by carbon dioxide treatment We show that epimerization offers a completely new approach to the chemical modification of carbohydrates. suggest
